FLUID-MOTOR.

Specification of Letters Patent.

Patented Feb. 25, 1919.

To all 'whom t may concern.'

Be it known that I, JAMES MUSE, a subject of the Dominion of Canada, residing at Quincy, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Fluid-Motors, of which the following is a specification.

This invention relates to a motor co1nprising a casing forming a circular chamber, and a wheel journaled in the casing and having a circular rim and buckets projecting therefrom into the marginal portion of the chamber, and adapted to be impelled by water, or other uid, under pressure, admitted to one portion of the chamber and discharged from another portion.

The invention relates especially to the form of the internal surfaces of the casing members and of the wheel rim, and is em-y bodied in the improved formation hereinafter described and claimed adapted to conline and direct the impelling fluid in the path of some of the buckets, without appreciable leakage or divergence fromv said path, and therefore, without loss of power, and to permit the scattering and free escape of the fluid when it reaches the end of said path, so that the rotation of the wheel is not impeded by the spent fluid.

Of the accompanying drawings forming a part of this specification,-

Figure 1 is an edge view of a motor embodying the invention.

Fig. 2 is a side view of the saine.

Fig. 3 is a side view of one of the members of the casing and the wheel thereon, the other side member being removed.

Fig. 4 is a side view of the other side member, looking toward its inner side.

Fig. 5 is a fragmentary section on the plane of line 5-5 of Fig. 3, showing portions of both members of the casing and a portion of the wheel.

Fig. 6 is a fragmentary section similar to Fig.V 5, on the plane of line 6-6 of Fig. 3.

Fig. 7 is a section on line 7 7 of Fig. 4.

Fig. 8 is a section on line 8-8 of Fig. 4.

Fig. 9 is a section on line 9-9 of Figs. 2 and 3, showing one of the wheel arms or spokes.

Fig. 10 represents inv perspective coinciding portions of the casing members looking toward the inner sides thereof.

The same reference characters indicate the same parts in all of the figures.

12 and 13 represent members of a casing forming a chamber adapted to inclose a wheel comprising a circular rim 14 and buckets 15 projecting outwardly therefrom. Each of said members includes a fiat circular side or body portion forming one of the side walls of the chamber, and an inwardly projecting annular marginal flange, said flanges meeting and beinglbolted together, or otherwise connected to form the circular marginal wall of the chamber. The body portions are provided with bearings 16 in which the wheel shaft 17 is journaled. The body portions or side walls of the casing are provided with internal fluid-confining faces 18, in close proximity to the lateral ends of a plurality of buckets, and with internalfluid-releasing faces 19 spaced from the lateral ends Vof another plurality of buckets.

The marginal portion or annular wall of the casing is provided with an arcuate internal water-confining face 20, preferably formed in two sections, one on the member 12, and the other on the member 13, said sections being abutted together and forming a face 2O which is in close proximity to the outer ends of a plurality of buckets. Said annular wall is also provided with an arcuate internal fluid-releasing face 21, also preferably formed in two sections, and spaced from the outer ends of another plurality of buckets.

The fluid-confining faces 18 and 20 cooperate with the wheel rim 14, in forming an arcuate raceway, adapted to confine an impelling fluid, and direct it in the path of a. plurality of buckets, without appreciable loss of power by leakage or deviation from said path.

The casing is provided with a preferably tangential fluid inlet 23 entering one end portion of said raceway. A jet of fluid is admitted through said inlet in the direction required to cause it to pass through the raceway and impel the wheel.

The water-releasing faces 19 and 21 constitute walls of an enlargement of the wheel chamber, and permit the fluid emerging from the raceway to scatter in various directions in said chamber, so that the fluid after performing its function does not impede the rotation of the wheel. The spent fluid is discharged through a relatively large outlet 24 communicating with the enlarged portion of the chamber.

Copiesof this patent may be obtained for The side members of the casing are preferably provided with arcuate flanges 25, whichV are coextensive with and project inwardly from'the fluid-confining faces 18, and are in close proximity to the inner surface of the wheel rim 14, said ianges preventing or minimizing inward leakage of fluid vfrom the said raceway, or between the edges of the wheel rim and the faces 18. As shown by Fig. 9, the wheel arms or spokes 14n are narrower than the space between the arcuate flanges 25.

Any suitable means may be provided for utilizing the rotation of the wheel through the wheel shaft 17.

I claim:

'1. A motor adapted to be driven by water or other fluid under pressure, and comprising a wheel having a circular rim and a seriesl of buckets projecting youtwardly therefrom, a casing forming a wheel chamber and including opposed spaced 'apart side walls, internal iuid-conning 'faces in close proximity to the lateral ends of the buckets, and internal fluid-releasing lfaces. spaced from said ends, yand an annular marginal wall having an arcuate internal fluid-confining face concentric with the wheel axis and in close proximity to the outer ends of the buckets, and an internal fluid-releasing face spaced from said ends, said fluid-confining faces f0rming a contracted portion of the chamber v and coperating with the wheel rim in providing an. arcuate raceway adapted to confine and direct lfluid in the path of' some of the buckets, while said releasing faces form an enlargement of the chamber permitting fluid to scatter from the path of the remaining buckets, an inlet passage communicating with one end portion of said raceway, and an outlet passage communicating with said enlargement.

2. A motor as specified by claim 1, the side walls being provided with arcuate flanges projecting inwardly from the fluidconfining faces of said side walls and co-` extensive therewith, Said flanges being in close proximity to the inner surface of the wheel rim, and preventing or minimizing inward leakage of fluid fromsaid raceway.

In testimony whereof I have affixed my signature.
